Terrestrial photogrammetry and the 3D scanner interface

Author(s): Pavol BUKOVAN

Abstract:
This article focuses on terrestrial photogrammetry and its applications to practice with the 3D scanner interface. Nowadays, the photogrammetry in a connection with the 3D digital spatial scanning is very demanding. It is used mainly for the reconstruction of historic buildings, but also for the construction of new projects. Photogrammetry consists of several methods and procedures that are directly influenced by software and hardware. The main areas of use are the construction, urbanism, criminal investigation, the medical, aviation and the space industry. Photogrammetry can be used for simple, but also for complex projects to create a visualization of changes, caused by human and natural activity.

Knowledge in a Scope of Information System Development

Author(s): Boris BUČKO, Katarína ZÁBOVSKÁ

Abstract:
The development of information systems (IS) scored several developmental stages that are characterized both in terms of their use as well as access to the solution. These stages influenced creation of different types of information systems for various applications. But what in the development of the IS is still missing is a clear connection to user requirements. This paper considers using ontology in some aspects of model driven development.

Post-processing of 3D scans in laser scanning

Author(s): Michal PALČÁK

Abstract:
The article focuses on Intelligent Transport Systems (ITS), which serve as a tool for improving the quality, safety and efficiency of transportation. These systems include a wide range of technology, software and infrastructure that make city travelling more efficient and better from the perspective of all stakeholders. ITS represent one of the main Smart Cities concepts. Through these new advanced tools, we can reduce adverse effects and in turn increase the desired benefits with regards to funding.

Computer-aided Design in Manufacturing Process Management

Author(s): Miriam FANDÁKOVÁ, Boris BUČKO, Katarína ZÁBOVSKÁ

Abstract:
Computer-aided design (CAD) is powerful tool, which helps designers and constructors with the designs of new products in all areas of industrial manufacturing. CAD is one of many inputs of manufacturing process management (MPM). MPM defines “how” a product is to be produced. It is a summary of inputs which help by production. CAD is divided to 2D and 3D modeling. There are many free and paid software applications which can be used by designing a product. 3D CAD applications with ability to create both 3D and 2D designs are widely used among the designers. This article gives an overview over history of 2D and 3D CAD software and their division.

Mapping in a 3D software environment

Author(s): Pavol KUDELA

Abstract:
Object modelling in virtual environment is one of the most important tasks. It plays an essential role in achieving the most realistic output, or similarity of a scanned object. There are many software solutions available on the market a user can choose from, such as an intuitive ribbon interface or a mapping option. These options are very important because they can influence the process of mapping an object and have an impact on time it takes to map the object. Not every software solution can map objects without difficulties. It is essential that the functions of specific software solutions provide sufficient options, for modifying the process of mapping and texturing as well. In case there are enough options, then it is only a matter of time and of how fast the final effect is reached.
